Special Note Regarding Forward-Looking Statements

This report contains forward-looking statements and information that are based on the beliefs of our management as well as assumptions made by and information currently available to us. Such statements should not be unduly relied upon. Forward-looking statements include statements about our expectations, beliefs, plans, objectives, intentions, assumptions and other statements that are not historical facts or that are not present facts or conditions. Forward-looking statements and information can generally be identified by the use of forward-looking terminology or words, such as “anticipate,” “approximately,” “believe,” “continue,” “estimate,” “expect,” “forecast,” “intend,” “may,” “ongoing,” “pending,” “perceive,” “plan,” “potential,” “predict,” “project,” “seeks,” “should,” “views” or similar words or phrases or variations thereon, or the negatives of those words or phrases, or statements that events, conditions or results “can,” “will,” “may,” “must,” “would,” “could” or “should” occur or be achieved and similar expressions in connection with any discussion, expectation or projection of future operating or financial performance, costs, regulations, events or trends. The absence of these words does not necessarily mean that a statement is not forward-looking.

Forward-looking statements and information are based on management’s current expectations and assumptions, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. These statements reflect our current view concerning future events and are subject to risks, uncertainties, and assumptions. There are important factors that could cause actual results to vary materially from those described in this report as anticipated, estimated or expected, as well as general conditions in the economy, capital markets, Securities and Exchange Commission (the “SEC”) regulations which affect trading in the securities of “penny stocks,” and other risks and uncertainties. Except as required by law, we assume no obligation to update any forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in any forward-looking statements, even if new information becomes available in the future. Depending on the market for our stock and other conditional tests, a specific safe harbor under the Private Securities Litigation Reform Act of 1995 may be available. Notwithstanding the above, Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), expressly state that the safe harbor for forward-looking statements does not apply to companies that issue penny stock. Because we may from time to time be considered to be an issuer of penny stock, the safe harbor for forward-looking statements may not apply to us at certain times.
